Kernrechtsfrage
Whether the factual findings about disproportionate self-defence were arbitrary
Extrahierter Entscheid
The challenge was purely appellatory and therefore inadmissible; the cantonal findings were not shown to be untenable.
Extrahierte Begründung
In criminal appeals, facts bind the Federal Court absent arbitrariness. The appellant merely substituted his own view of the evidence without demonstrating manifestly unsustainable reasoning.
